摘　　要：研究了机抖激光陀螺抖动偏频量与温度之间的关系。通过大量的重复性高低温实验,证明了抖动偏频量与温度的线性关系,并得到了拟合直线表达式。结果表明,抖动偏频量与温度具有较好的线性关系,而且具有较好的重复性。同时用抖动偏频量对陀螺的零漂进行补偿,提高了陀螺的精度。The relation of frequency Offset to temperature is studied. It has been shown that frequency offset is proportional linearly to the temperature via lots of high- low temperature experiment repeated, and the linear expression is achieved. The result show the RLG＇ s precision can be improved by frequency offset compensation instead of temperature compensation.
